LEVEL 'AN PLUMB-R-ULE.

Specification of Letters Patent.

Patented Aug; 4, 1908;

Application filed March i6, 1907. Serial No. 362,716.- i

To 1 1 07mm, it nun consent:

Be it known that l, WILLIAM W. S'rrrr'rman, a citizen of the United Statespresiding at v\llentown, in the county of Lehigh and State of Pennsylvania, have invented 'a new and useful lmprm'crnent in Levels and Plumb-Rules, oi /which the following is a specification. 7

This invention relates to spirit levels and more parth-ularl'v to combined spirit level,

plumb and rule; the-object being to provide the instrumentwith adjustable vials so that bysetting the vial to the rise or fall desired,

a. pavement. )l )e brid e or anv other kind l i n r of work can be readily graded.

l'ith this and other objects in.view, the inventionconsists in the novel features of construction, combination and arrangementof parts hereinafter fully described and pointed out in the claims.'

25. larged view of a portion of the level.

In the. drawing forming a part of this speci- 0 In the drawings indicates a stock which may be of any length desired, provided with a central leveling opemng A and a plumbing penin ad acent one end, both of which are provided with inwardly pr jecting por- 3-5 ti ns, to which my improved leveling mechanism is secured, the description of one being stillicient for both as they are formed exactly atike.

Secured in the opening to the sides of the 40 imvardlv projecting portion by screws, are

dial plates 13', which are divided into sixteen equal divisions from rightto left, which mdicat-rs the rise and fall of one eighth of an inch, in! every running foot of the. stock as 4-5 will be hereinafter fully described.

crewt extends through an opening in each of the plates no the inwardly projectin portion on which is mounted a plate .0 provided with a bifurcated Upper end form- .50 mg arms C which are bent. around the ordinary spirit vial l), which securely holds it in place aml at the same time allowing it to be readily seen from below wh n using the level over thehead.

3-5 A curred slot C is formed in the plate through which extends a. set-serew E working-through an opening into the inwardly projecting portion of the stock so that the plate. -an be secured in any position desired b tightening the screw. Secured on the lower end of the plate b atlunnb-screw F is a pointer l wt'mking o\'c1 the gradnations of the. dial so thatv by setting the pointer forinstance to one-fourth in a four-foot stock, the rise and fall-would be one inch in four feet or i t to one. and a hall birth, the. rise would. be six inches in four feet. I

One end of the stock is reduced by rabbet- 'ing the sides and cutting the corners ull' obliquely, over which is secured a.eap ll, the walls of which are provided with oppositely disposed slots ii. in which the end of the plumb cord I is adapted to be secured by rolling the cord through the same, until the not at the end of the'cord engages the end of the cap, and securely holds itin position. The cord extends downward through a slot in the head of a. screw J secured in the. stock havinga bob at, its lower end, said screw serving to hold the weight-out from the. stock. It will be r adil vsecn that it each of the vials should become broken a plumb and bob could be readily attached and used until the vial could be re ilaced.

Having thus hilly described my invention, what I claim as -new and desire to secure by Letters Patent isz--- I. in a device of the kind described, the combination with a stock provided with an opening having an inwardly projecting portion, of a dial secured in said opening over said inwardly projecting portion, and providcdwith spaced openings, a screw extending through one of said openings into the stock, a plate iivo-ta-lly mounted on said screw and provided with a curved slot, a. setscrcw extending through said slotin said plate, and through another of said openings in said dial into said sto k for holding in ad justment said plate, said plate having a bifurcated upper end t'ornnng arms, a spirit vial carried by said arms and secured in said arms by bending the arms around the vial, and a pointer detachably secured on the lower end of said plate working o\ 'er the graduations ol' the dial, for the purpose described.

2. in a device of the kind described, the combination with a stock provided with transverse and longitudinal leveling and plumbing o oem'ngs having inwrdlylprojectmg portlcns, of graduated dials secured to sald ort-ions, plates gi-votally mounted on tslots, screws secured said ials provided wi in said dials extending through said slots, arms projecting upwardly from said plates carrying Vials, and pointers moun fsd on I plates working over the graduations dials for the purpose described.
